Answer 1

360 miles

Explanation:

A car rental company charges a daily rate of $39 plus $0.20 per mile for a certain car. Suppose that you rent that car< for a day and your bill (before taxes) is $111. How many miles did you drive?

this can be represented by the equation:

39 + 0.2x = 111

subtract 39 from both sides:

39 + 0.2x- 39 = 111 - 39

0.2x = 72

divide both sides by 0.2:

0.2x/0.2 = 72/0.2

x = 360 miles
